This invention relates to a 'rapid cutting machine.

One of the objects of my invention is 'the production of a simple and eiiicient machine which will cut anyI gauge metal very rapidly by using an air hammer for 'vibrating the cutting element, of my machine. l i

Another object of myy invention is the construction 'oi a 'simple and eiii'cient cutting` machine ,that can be easily clamped or bolted to fa work bench. l

A still further object "of my invention is the vvconstruction of a cutting machine in which the cutting element is of a novel and eicient construction, being 'cushior'ied` in 'a practical m'ai'inerby la spring and adapted to have easily connected thereto an air hammer, for vibrating or oscillating said 'cutting element.

With the foregoingfand otherfiobjec'ts in view, my invention comprises certain' novel constructions, combinations and arrangey ments oi parts as will be hereinafter fully described, illustrated in the accompanying dni-wings, and more particularly pointed out in the appended claims.

In the drawings 'z j Figure 1 is a view in side elevation of a machine constructed in accordance with thepresent` invention, while M p Figure isa vfront view of the saine.

Figure?V is a sectional View taken on line 7-7,F,ig. 1, and looking in the direction of the arrows.

, Reierring te the drawings by numerals, 1 designates thebase of the machine provided with upstanding head 2 at oneJ lend and at its' oppesite end with 'bottom die 3. .T hebase i is provided with a plurality of vertical aper-V tures 4 through l'which may vextend suitable boitsiior fastening the machine to a bench r '1930. serial No. 464,399.

The head 2 is grooved at 5 in which isrs'lidably mounted vthe adjustable plate 6. Plate r 6 is provided with a screw socket? in its inner end, Fig. 3. in integral upstanding il'ange 8 is formed on head 2 at its outer end, and

threaded through this flange is screw `9, carrying a lock nut 10. Screw 9 vextends into said socket Vfor adjustingthe platey @long itudinally upon the head 2. The plate i`6 is provided with a large vertical 'aperture or lslot 11 over which is'placed a washer 12. ,Through washer 12 and the aperture 11 eX- tends bolt 13. This bolt 13 is threaded into head 2 so that the adjustable plate 6 can be locked against movement in an adjusted position, for the purpose hereinafter described.

On the outer end of horizontal "plate Gis' formed a head 14, in which head isla vertical spring socket 15. `This head 14 extends-above the upper Lface of plate 6, and around the head isplaced the lower end of channel body 1h; this body 16 is substantially U-shape in hori-v zontal cross section, Fig. '.7. Rising from body 16 is vertical bracket 17. carrying);hori-V zontal bracket 18 in which is positioned air hammer 19.

' rEhe lower end oiibody 15 is secured upon the head 14 bya bolt 20, while the Vsides '21 of body 16 extend down against the sides of head 14 and plate 6, as shown in Figure l.

A cutting tool 22 is placed within the channel body 16; This cutting tool is provided a" its lower end with a cutting edge '23 and on its upper end with sha'nli24. The lower cutting edge 2B col-operates with die 3 lfor cutting or shearing metal; the desired us'tmeiit between cuttingedge 2,3 and die 8 can `be "ob-v tainedto a nicety by the adjustment of screw 9 and the plate 6 upon head 2.' The air hammer is mounted upon shank 24, Figs. 1

A front guide plate 25 -is fastened by bolts 26 to the front edges of the channel body 16, whereby the lcirtting tool 'e2 can Slide upon the body but will not be accidentaily displaced. The front guide plate-is fprovioled with an elongated slot 27 in which works/the heads of the bolts 28. Upon the inner ends of boite 28 is 'fastened a bess or bioek. 29. Thisbloelr 29 moves syiichrcnously-with the Cutting teol. A centering 'so is seatedV in lili) spring socket 15 and bears at its upper end, against the bottom ofblock 29, so that the tendency is to return the cutting tool to its upper position at all times. In the upper end of channel body 16 is a horizontal bridging web 3l, Fig. 3. A cam 32 is placed against web 3l and behind the vertical bracket 17 a bolt 33 extends through the upper end ot brace '34, also through the bracket V1T and cam 32 and is threaded into web' 8l. rIhe lower Yend of brace 3a'- is fastened by bolt 35 to the top of the adjustable plate 6. i It will, therefore, be seen that the plate channel body 1G and cutting'tool 22 are synchronously adjustable upon the base of the machine.

,The cam 82 operates upon the block 29 to manually force the cutting tool 22 downward ly when the operator is testing the machine, but when the handle 36 oi cam 32 is swung upwardly to the dotted position shown in Fig. 2, the spring 30 will force the cutting tool upwardly so that the work or metal to be operated upon can be placed in position upon the bottom die 3. Y

In operation, with the cam in its normal position as shown by dotted lines in Fig. 2, the air hammer 19 will operate the cutting tool while at the same time, spring 30 will always exert an upward pressure on said tool,

- l which returns it to its upper contacting position with the air hammer; the blow of the air hammer being downward, with the spring 80 for keeping the shank 24 in i engagement therewith. Y

Iliile I have desciibedthe preferred embodiment of my invention and illustrated the sameV in the accompanying drawings, certain `minor changes or alterations may appear to one skilled in the art to which this invention relates, and I, therefore, reserve the right to make such changes or alterations as shall Vfairly fall within the scope of the appended claims.
